In the design workspace. The loft command blends multiple profiles or faces
00:09
and transitions them into smooth shapes between the profiles or faces.
00:14
Loft can create new solid bodies or add
00:16
and subtract material from existing solid bodies.
00:20
Loft creates complex shapes between multiple profiles. In one step,
00:25
let's use the loft command to create the tapered shape
00:27
for the inlet outlet component for the small pump.
00:31
Notice that both profiles include geometry for hardware
00:34
clearance and the relief has a slight taper
00:37
on the toolbar on the solid tab. Click loft,
00:41
the loft dialogue displays
00:44
select both profiles.
00:46
The preview shows a straight transition between the two profiles
00:50
in the dialogue. Click the drop down list next to both profile one and profile two
00:55
and enable the direction option.
00:58
Notice that two new options are enabled, take off weight and take off angle.
01:04
Take off weight is a unit less factor that determines how far
01:07
the section shape extends before it transitions into the next shape.
01:13
Take off angle represents the transition angle between the profile
01:16
or guideline and the faces created by the loft.
01:20
The default value of zero degrees provides a perpendicular transition
01:25
for this loft.
01:26
We'll use a joint operation to merge the new feature with the existing body.
01:33
You can use an existing planar face for a profile.
01:37
Additional options are available depending on the selection set.
01:41
For example, tangent G one
01:44
and curvature G two.
01:49
You can also laught to a point
01:52
enable point tangent to soften the transition,
01:57
enable direction to set the weight and angle.
02:05
Here are some of the other loft settings you can use to control the shape.
02:10
Use loft with the centerline option to use
02:12
a selected center path to control the shape.
02:16
In this example, the loft creates a new body.
02:24
Use loft with rail guides to use one or more paths to control the shape.
02:36
Use loft with a cut operation to remove material from a body.
